The study examined 10,711 adults aged 19-64 with data from the Korean National Health and Nutrition Examination Survey. One challenge was to separate out other indicators. For instance, the research showed, "Participants who frequently consumed instant noodles (≥2 times/wk) and those in the highest quintile of the MP [meat pattern] were younger, more likely to be current smokers, drink more alcohol, be less physically active, and have low carbohydrate intake in both genders."
That presents challenges in attributing risks specifically to instant noodles. Nonetheless, researchers believe that there is significant support for their belief that instant noodle consumption is linked to cardio-metabolic syndrome. "This research is significant since many people are consuming instant noodles without knowing possible health risks," Dr. Shin said. "My hope is that this study can lay a foundation for future research about the health effects of instant noodle consumption."
